Description

one

This invention relates to devices for exciting oscillations.

Hydraulic vibrators are known that contain a double-acting piston actuator, the working cavities of which are connected by separate pipes to the cavities of the rotary compressor.

The goal of this is to improve reliability and ease of operation.

This is achieved by the fact that the ornus of the rotary blower is made with a sleeve mounted on rolling bearings, inside of which the rotor equipped with louisers is located eccentrically to the axis of its rotation, the channels parallel to the axis of its rotation are symmetrical with respect to the blades, each of which is These are part of the pipeline, connecting op; iHOHapHO corresponding cavities of the expeller mechanism and supercharger.

Ia fpg. schematically shows the described vibrator, a general view; in fig. 2 - supercharger, cut; in fig. 3 is a section along A-A in FIG. 2

A hydraulics vibrator consists of a rotary supercharger having a body / with a cover 2, inside which, on rolling bearings 3, for example roller, is installed a sleeve 4 with a spaced inside it eccentric to its axis of rotation with a rotor with blades 6.

The rotor shaft is mounted on bearings 7 and symmetrical with respect to the blades channels S, connected parallel to the axis of its rotation, are made in its body, connected through the liquid extraction heads 9 of nozzle 10 and pipes // to the cavities of the double-acting piston cylinder 12.

The blades of the irreversible spring 13 located in the slots of the rotor are in constant contact with the inner surface of the sleeve and divide its internal volume into two halves, each of which communicates with one of the channels.

A hollow rod M with a piston 15 is placed inside the cylinder of the double acting actuator. At the ends, the cylinder is closed with a blind 16 and 17 valve covers connected to each other by a pipeline 18. The cavities for the working fluid of the second sealing pipe line are interconnected in front of: With a cork tap 19.

Hydraulic vibrator works as follows.

When the rotor rotates 5, due to its eccentric position relative to

the axes of the crankshaft 4. volumes of the cavities, 1 located on both sides of the blades 6. Both are sinusoidal from the minimum to the maximum, and the sum remains unchanged. The working fluid is therefore alternately pressed and sucked through the channels 8, the head 9, the fittings 10 and the pipelines 11 of the working cavities of the cylinder 12. An oscillating drive mounted on the rod 14 is a piston 15 with a frequency equal to the angular velocity of the rotor.

Since the sleeve rests on the rolling shaft 3, when the rotor 5 rotates the cavity 6, pressed against the inside of the surface of the sleeve 4, the springs 13 carry it away, which dramatically reduces wear on the blades and friction losses.

Subject invention

A hydraulic vibrator, containing a double action porsche actuator, the working cavities of which are connected by separate pipes to the cavities of the rotary blower, characterized in that, in order to increase the reliability of operation and ease of operation, the rotary blower housing is made with a sleeve installed on the rolling bearings inside where the axis of its axis is eccentric, the rotor is fitted with a rotor, equipped with a blade, and in the body of the rotor shaft are located

Parallel to the axis of his rise, the channels are symmetrical with respect to the blades, each of which is a part of the pipeline connecting in pairs the corresponding cavities of the additional mechanism and Supercharger.
